The present application provides a box device. A hinge assembly of the box device is provided with a first sliding rail and a second sliding rail. The first sliding rail extends along a first reference ellipse, and the second sliding rail extends along a second reference ellipse. When a door body blocks an opening, the part of the first sliding rail that is away from the box and the part of the second sliding rail that is away from the box are both away from a pivoting side, and the door body moves towards a target side of the box body during a process from blocking the opening by the door body to opening the door body relative to the box body, to reduce the extent to which the door body exceeds an outer sidewall of the box body.

A self-aligning pin. The pin has a shaft and a curved end section with the diameter of the shaft and the curved end section being equal to one another.

A box device includes a hinge assembly, and the hinge assembly is provided with a first sliding rail and a second sliding rail. The first sliding rail extends in a straight line; the second sliding rail extends along an ellipse. When a door body blocks an opening, the first sliding rail is obliquely arranged with respect to a plane where the opening is located, and the part of the second slide rail away from a box body is away from a pivoting side with respect to the first sliding rail, and the door body moves towards a target side of the box body during opening door body with respect to the box body from a state where the door body blocks the opening, to reduce the extent to which the door body exceeds an outer side wall of the box body.

A lever pushes a latch drawn into a hook accommodating space in a latch holder in a direction where a door opens is installed in the latch holder, and the latch is released from the latch holder using the lever. The door that is opened by an initial opening angle by the latch holder releasing the latch automatically opens by self-weight of the door.

A synchronization rod for furniture drives for the synchronous moving of movable furniture parts, includes a coupling portion for connection to a furniture drive and a synchronization portion along a length of the synchronization rod, more particularly arranged between two opposite coupling portions. The synchronization portion, as seen in a cross-section taken orthogonally to the length, has a first outer contour portion in the form of a circular segment and a further outer contour portion, preferably adjacent to the first outer contour portion, having a geometry in a form that is not a circular segment. The circular segment comprises an angular range of between 250 and 330 and/or an angular range of between 180 and 350, and the further outer contour portion is arranged exclusively on one side of the synchronization rod.

A door closer, comprising a door closer housing mounted to one of a door frame or a door surface and a linkage arm for pivoting the door between open and closed positions. The linkage arm has a first and second end, the first end mounted to the other of the door frame or the door surface. The door closer includes a rotatable connector between the linkage arm and the door closer housing, the linkage arm second end engaging with the rotatable connector. The connector has a rotatable body portion and head protrusion substantially secured in a female receptor to transmit rotation about a longitudinal axis of the connector. One or both of the head protrusion or female receptor has a curved profile and is further movable with respect to the head protrusion to permit limited rotational misalignment of the linkage arm on any axis perpendicular to the connector longitudinal axis.

The invention provides a modified box-shape safe that includes a cabinet having an open front contiguous with an open oblique side obtusely angled relative to the open front. The safe cabinet is formed by two vertically oriented rectangular sections that adjoin to form the cabinet's back and side wall and two horizontally oriented trapezoidal sections that adjoin adjacent horizontal edges of the back and side walls to form the cabinet's top and bottom. The open front and contiguous open oblique side of the cabinet is closed using a safe door having a rectangular front section adjoining an oblique side section obtusely angled relative tot the front section. The door is pivotably connected to the cabinet so as to open from the oblique side section.

A door opening/closing device includes a shaft member installed on a first door panel side so that it cannot rotate. Both ends of a torsion spring in the door opening/closing device are latched to a second door panel side via torsion spring latching walls, and a center portion of the torsion spring is latched to the first door panel side via a latched member, a latching portion, and the shaft member. When the first door panel and the second door panel are pulled from the state in which the doorway is closed, the first door panel and the second door panel fold about an outside cylindrical member as center. The outside cylindrical member rotates relative to the shaft member. First and second coil portions deform elastically in the direction that they are each wound tighter, and the first and second door panels are opened and the doorway is opened.

The invention relates to a flap drive system for a flap which is movably mounted on a furniture carcass. The flap drive system is arranged on a sidewall of the furniture carcass. The flap drive system includes a mechanical actuating unit having an actuating arm that can be connected to the flap and an accumulator acting upon the actuating arm, and an electric drive, fastened on the mechanical actuating unit for driving the flap. The electric drive has at least one electric motor, and a gear stage which allows the transmission of force from the electric drive onto the mechanical actuating unit. The gear stage is designed as a separate component, and has a housing that is independent from the mechanical actuating unit and the electric drive or an independent mounting plate.

Apparatus and associated methods relate to a sliding door closure system. The sliding door closure system includes a safety cushion device configured to be suspended. The safety cushion device may advantageously prevent injuries to a person's hands, feet, fingers, body parts and/or injury to pets. The sliding door closure system includes an anchor situated in a vertical closure track of a sliding door configured to be coupled to the suspension suspending the safety cushion device. In a closure mode, the safety cushion device may be displaced out of the vertical closure track of the sliding door so the sliding door may abut the vertical track frame. In a safety mode when the sliding door is closing, gravity urges the safety cushion device into a position separating the sliding door from a frame so that the safety cushion device absorbs the impulse of the sliding door.
